Did Walphie End Up Becoming a Rejected Muppet?

Sometime in Season 33, IIRC, Papa Bear gets Baby Bear a pet: a parrot whom he names Ralphie (and also passes on his speech impendiment to)... it seems like Ralphie (or Walphie) made sporadic appearances over the next couple of seasons, whenever there was a story that had to do with pets and animals, he made a random appearance by attending the Flyers' Club Roost in honor of Grover by himself, then it seems like he just disappeared, so I'm just wondering, did he end up becoming one of those "Rejected Muppets" that get sent overseas for international co-productions?

On the same subject, what about the other characters' pets? Has Telly mentioned Chucky Sue recently? Has Zoe aggravated Elmo to no end with Rocco as of late?

Ralphie hasn't been used since the resource video "Math is Everywhere," without Baby Bear, but hanging with Telly. I don't know if Telly has mentioned Chuckie Sue lately, but there was a Rocco episode this past season ("Rocco's Boat").
